A recent lab- oratory-scal study13 applies anammox bacteria in mainstream wastewater treat- ment. A granular sludge sequencing batch reactor (SBR) mixed ammonium and acetate at a COD:N ratio of 0.5 (so heterotrophs do not out compete the anam- mox bacteria) using nitrate from the previous SBR cycle at 18°C. The work from Winkler et al. and other results from current research conducted by Hampton Roads Sanitation District and DC Water can serve as the baseline for a Phase II anammox analysis. Because of the significant advantage of this process, it would bring major energy-savings benefits to the industry. The current plan is to imple- ment anammox at demonstration-scale on the effluent of the anaerobic MBR. Pasteurization The pasteurization process is at demonstration scale (400 gpm) to disinfect filtered secondary effluent cost effectively to reclaimed water standards10. The unit is fully automated, with online monitoring of temperature, energy use, and control. The demonstration unit is anticipated to run into 2013. Other Technologies Several gasification processes are in operation nationally and internationally. These processes claim large net energy gains, though little to no peer-reviewed analysis has been conducted. Audits of one or more facilities is recommended. The electrocoagulation process has the potential for energy efficient coagula- tion/filtration/disinfection to meet stringent reclaimed water standards. Limited bench scale testing of electrocoagulation of conventional secondary effluent and of anaerobic MBR and anammox effluent is recommended. Aerobic biofilm reactors for secondary treatment show promise; the SABRE process will be installed at a demonstration-scale in late 2012 or early 2013. An audit of this facility is recommended.
